Simplified Interfacial Area Modeling in Polydisperse Two-Phase Flows under Explosion Situations

The aim of the present work is to account for polydisperse effects in a two-phase flow with simple and fast method. Polydisperse flows arise numerous applications. Fire sprinkler systems are relevant examples as they release clouds droplets. Another example created by detonation an explosive charge surrounded liquid layer. In such situation, material interfaces initially consists carrier gas phase involving many droplets various sizes. Spherical particles or usually assumed computations. When dealing explosion situations both dense dilute regimes, multiple particle diameters can be addressed but at price introducing additional equations that describe mass, momentum energy balance classes. Consequently, computation time needed address numerical resolution increases tremendously. Under diameters, method becomes intractable reduced single diameter, which often insufficient. A simplified approach developed substantial number different sizes few extra computational cost. said velocity temperature considered all spherical particles, regardless their diameters. This type modeling seems apt target situations. focus placed on interfacial area, main parameter involved coupling two phases. work, Gamma-like continuous probability distributions particles. size distribution only summarized specific yielding consequently code modifications while taking into aspect flow.
